Drawing circular genome maps...? - (Jan/08/2007 )

Anybody got any idea what software is used to create those circular genome maps one sees in genome sequencing papers (e.g. this one, this one, or this one)? I'm currently playing with CGView, but it's not quite what I'm looking for...

Really, all I need to do is generate a static image for a PowerPoint presentation... I don't need comparative analysis with other genomes or anything, just a circular feature map...

Suggestions welcomed and appreciated.
